> Java being slow is most often a pebcak scenario

Am I the only one who thinks "pebkac" is a self-own? If you're blaming your users for the tool, it feels like maybe your tool is just hard to use properly. I have no doubt that there are big, fast, low latency Java systems out there, but why does it take so much extra effort to build these systems in Java compared with other languages? Maybe it would be better to have competent developers focus their attention beyond managing Java's shortcomings?

I'm not even hating on Java here--I actually like the JVM quite a bit, but blaming users feels like an implicit admission.
